I'm planning a trip to Switzerland in September and want to see if I can weave a visit to Jungfraujoch into my schedule. I am wondering if 2 hours on top of the mountain is enough. I'm arriving at Interlaken from Geneva around 12:50 according to the timetable so the soonest I can get to Jungfraujoch is 15:22 and the latest train leaving Jungfraujoch is 17:45, leaving me only 2 hours and 20 minutes at the summit. Is it too short to make it a memorable visit? This is the only time I can fit it in my schedule so if I don't go then I won't be able to go at all. I'm not that interested in the ice palace and can skip that if necessary, just want to see the view up there.
thank you very much for your help.
